The image below illustrates what happens when two spiral galaxies crash into one another.....
They are now somewhat less spiral shaped than before the crunch and you can also see the debris trail between them. Apparently, they are now heading away from each other. The larger galaxy is NGC4490 (aka the Cocoon Galaxy) and the smaller one NGC4485.
Whilst this is an LRGB image, I was quite pleased to see some Ha regions clearly visible. The image represents just over 12 hours integration time and was taken with my Esprit 150.
